MOLD.

Specification of Letters Patent.

Patented Feb. 18, 1908.

Application filed February A. 1907. Serial No. 355,570.

To all whom it may concern:

Be it known that 1, WILLIAM J. MILLER, a citizen of the United States, and'a resident of Gofieyville, in the county of Montgomery and State of Kansas, have invented certain new and useful Improvements in Molds, of which the following is a specification.

This invention is an im )rovement in molds for glass and other artic es, being especially designed for use on glass molds; and the inventlon consists in certain novel constructions and combinations of arts as will be i hereinafter described and c aimed.

In the drawingsF ig ure i is a top plan view of an a paratus embodying my rnvention, the mo d being closed. Fig. 2 is a detail topplan view showing the mold open. Fig. 3 is a side view of the apparatus, the mold being closed and parts being shown'in section. Fig. 4 illustrates a somewhat diiierent construction for locking the mold sections closed.

The mold sections A are semi-cylindrical in form and are provided at their meeting edges with rabbeted joints a which operate to brin the sections into perfect alinement I when. closed. On their outer sides the sec- ,ma be interchangeably used on different down into the socket E in the base E. The

lugs A are arranged at approximately diametrically opposite points and the hinge being made separate irom the mold sections mo d sections so the molds may be renewed or replaced whenever desired.

The arms C of the yoke O are pivotally connected at b with theouter section B of the adjustable connection B, the inner sections 13 of said connections being pivoted atb in'connection with the mold'sections, as best shown in Figs. 1 and 2 of the drawings. The yoke arms C are provided at their inner sides adjacent to their extremities with the forwardly facing shoulders C which abut the connections B when the yoke is pushed forward to the position shown-in Fig. 1 and limit the forward movement of the yoke to prevent its being carried too far beyond the dead center.

By thedescribed construction it will be noticed that the movementof the yoke C in a direction radial to the mold will tend to positively open and close the mold by swinging its sections upon the pivot D of the hinge and that when the mbld is closed the yoke beingpushed to a point near to or at or be yond the dead center, the mold will be posi tively locked so that no amount of pressure therein can force its sections apartand yet a slight rearward movement on the yoke will release the mold sections and will then per mit said sections to be opened wide, as shown, in Fig. 2 by continuing the rearward movement of the okej It will be noticed that the opposite arms of the yoke are rigid with each other and that the yoke is moved bodily in a direction radial to the mold. Means are rovided for re tracting the yoke to open t 1e mold sections and for advancing the yoke to close such 30.

sectional employ s'prings F on rods H, and a roller G which may be operated upon by a cam lever or may be operated by hand power or otherwise as desired for advancing and retracting the yoke.

v In the construction shown in Figs. 1, 2 and 3, the rods H are connected at oneend H with the roller carrier, I being preferably screwed into said roller carrier I, as shown in Fig. 3, and sliding at their other ends looselythrough openings provided in connection with the yoke O and preferably in a block C secured on the under side of the yoke at'the juncture of its arms, s rings F 0 crating on the rodsJIbetween tie yoke b ook C and nuts II on the rods H, as best shown in Figs. 2 and 3, the springs forming a yielding connection between the operating carrier or cross head I and the, yoke to cushion the operation of the yoke as will be understood from Figs. 1 and?) of the'drawings.

Theroller carrier or cross head is-guided in alinement with the pintle D 0 the hinge. between the mo1d,sections' and this is effected in the construction shown in Figs; 1 and 3\105 by means of a pin '11 on the under side of -i'the carrier I operating in a slot K in la bradket l K mounted on the base E, see Figs; 1 and 3. In operation and as best illustrated in Fig.

1, it will be noticed that when the mold-1s closed the yoke 'is moved to or nearly to or past the dead center of the mold thus locking v are advanced the mold sections wil pressed to and locked in closed position and the mold sections securely together.

. the dead center thereof to lock the sections of the mold in closed position. In this construction shown in Fig. -l, the arms of the yoke are not connected positively with the mold sections but have a sliding engagement therewith so that when the arms otthe oke be means are provided whereby as the yoke is retracted it will open the mold sections. The specific construction shown in Fig. 4 so far as it differs from that shown in Figs. 1, 2 and 3 is not claimed herein, but forms the subjectmatter of a separateapplication for atent filed by me in the United States l atentOiiice, February 4, 1907, Serial No. 355,571.

\Vhat I claim isl. The combination of a base, a mold hav ing detachable sections, a hinge for said mold having a pintle connected with the base and arms secured to'their respective sections of the mold, a yoke having its arms rigid with each ether and embracing the mold, links connecting the mold sections with the yoke arms a1 d pivoted to such parts, said links being m: .de in sections adjustably connected and the yoke being provided. with shoulders to engage said links whereby to limit the advancing movement of the yoke, a reciprocating carrier for moving the yoke, and springs between t 1e said carrier and yoke, substantially as S( t forth.

2. A m )ld made in detachable sections combined with a yoke movable bodily in a direction iadial to the mold and having its arms rigid with each-other and embracing the mold and arranged at the extremities of said arms .oextend adjacent to or past the dead center of the mold and lock the sectrons therec f in closed position, substantially as set forth.

3. The combination with separable mold sections, of .i yoke open at the end for opening and closing said sections and with the extremities of its open end movable in the closed position of the sections to a point adjacent to or past the dead center thereof whereby to lock the sect ons from opening until the yoke is retracted, substantially as set forth;

l.- The combination of separable mold sections, and a yoke connected therewith to operate the same and open at one end and having its arms rigidly connected. an 91"- This is l ranged at their extremities to operate the mold sections and means for moving the yoke in a direction radial to the mold, substantially as set forth.

5. The combination with separable mold sections, of a yoke open at one end and hav-v ing its arms rigid with each other and free at one end and embracing the mold and connections between the free ends of the yoke arms and mold sections and pivotally connected with suchparts, substantially as set,
